Abstract: Systems and methods for switching a computing device from a low-power state to a high-power state are provided. In some aspects, a method, implemented on a power management processing unit of the computing device, includes receiving, while the computing device is in the low-power state, a first audio signal. The method also includes verifying the first audio signal based on an audio signal key. The method also includes providing, in response to verifying the first audio signal, instructions for switching the computing device from the low-power state to the high-power state.

Abstract: The computing device includes a speaker, a transducer configured to utilize a surface in contact with the portable computer to generate an audible sound, a detector configured to determine at least one characteristic of the surface based on at least one received sensor signal, and a controller configured to select at least one of the speaker and the transducer for audible output based on the at least one characteristic of the surface.

Abstract: A system for porting a speaker through a keyboard module and a backlight module is provided. The system includes an enclosure, the enclosure configured to mount the keyboard module, the backlight module, and the speaker thereto, wherein the speaker is disposed under a portion of the keyboard module and the backlight module. The system also includes a port path for porting the speaker through the keyboard module and the backlight module, the port path extending from the speaker to an outer surface of the keyboard module, wherein a first portion of the port path includes a passage in the enclosure, the passage disposed adjacent to an edge of the keyboard module and the backlight module, and wherein a second portion of the port path includes a periphery of a key of the keyboard module.

Abstract: In some implementations, a device for providing dual uplink processing paths may include a human listening (HL) input processing unit configured to receive an audio stream and pre-process the audio stream to create a first audio signal adapted for human listening via a first uplink processing path, a machine listening (ML) input processing unit configured to receive the audio stream and pre-process the audio stream to create a second audio signal adapted for machine listening via a second uplink processing path, and a network interface unit configured to transmit the first audio signal via the first uplink processing path and transmit the second audio signal via the second uplink processing path to a remote server.

Abstract: Apparatuses that provide a bone-conduction speaker arranged to be located behind the ear are described herein. An exemplary apparatus may include: (a) a glasses-style support structure comprising a front section and at least one side section; (b) at least one bone-conduction speaker; and (c) a member having a proximate end and a distal end, wherein the proximate end is attached to the at least one side section, and wherein the at least one bone-conduction speaker is attached to the member at or near the distal end; wherein the member is arranged on the at least one side section such that when the glasses-style support structure is worn the member: (a) extends to the anterior of the at least one side section and (b) locates the bone-conduction speaker posterior to an ear.

Abstract: A system includes a first housing that houses a plurality of mechanical keys. A first microphone that is configured to detect a dynamic noise is located within the first housing and under the mechanical keys. A second microphone is configured to detect acoustic waves that include speech and to convert the acoustic waves into an electrical audio signal. The dynamic noise is not associated with the detected speech. The system further includes a dynamic audio signal filter that is configured to suppress, in the electrical audio signal, dynamic noise, and the dynamic audio signal filter is activated in response to the first microphone detecting the dynamic noise.

Abstract: Exemplary wearable computing systems may include a head-mounted display that is configured to provide indirect bone-conduction audio. For example, an exemplary head-mounted display may include at least one vibration transducer that is configured to vibrate at least a portion of the head-mounted display based on the audio signal. The vibration transducer is configured such that when the head-mounted display is worn, the vibration transducer vibrates the head-mounted display without directly vibrating a wearer. However, the head-mounted display structure vibrationally couples to a bone structure of the wearer, such that vibrations from the vibration transducer may be indirectly transferred to the wearer's bone structure.

Abstract: A vector signal processor (80) can include a digital to time converter (DTC), an RF memory (RFM) or an electronically tunable transmission line (ETTL) (82), a mixer, or other phase shifter (70) for receiving an output of the DTC or the ETTL, and a controller for selectively controlling the harmonic processing of the DTC, RFM or the ETTL and the phase processing of the mixer. The vector signal processor can uncouple a relative phase of a fundamental signal with respect to harmonics of the fundamental signal. The vector signal processor uses selective phase processing of the fundamental signal and related harmonic components. In a specific embodiment, the vector signal processor cancels harmonics of the fundamental signal and more specifically can cancel a third harmonic of the fundamental signal.
